The load is 3 kW/h, the power consumption duration is 24 hours, and the electricity consumption is 72 kilowatt hours per day. It requires photovoltaic solar energy production equipment of around 20 kW, occupying 180 to 200 square meters of roof space (flat roof). ). If there is mains power, it is recommended to do so and the off-grid investment is slightly higher and the battery expense is not minimal.
How much does a three kilowatt home solar power generation cost?
Home solar power generation, 3 kW, generates 20 to 24 degrees per day, maximum load 4,000 W, maximum instantaneous load 8000W. , automatic power supplementation, if connected to the grid, the cost is about 25,000, and if it is off-grid, it will cost about 35,000 if connected to the network, the remaining energy will be recycled by the State. , and it will be recovered according to the local electricity price + pprice of the national subsidy. The payback time is typically around 6 years, and the payback time for off-grid will be longer. Some are suitable for places without electricity or with inconvenient access to electricity.
How to configure 3 kW solar power generation
First of all, it is recommended to find a first-line manufacturer, such as Yingli, big brands like JA Solar and Jinko A three-kilowatt power generation system typically costs around 20,000 yuan and uses Yingli A1-level battery panels. You need to be sure of this when purchasing battery panels. Be careful not to be cheap, you may come across fakes or poor quality ones. products
The configuration of 3KW solar power generation is as follows:
12 250W photovoltaic panels, 3KW inverter, Several support, some DC and AC cables, electric meters, cement stones (for fixing supports) and some other small accessories. You don't need to buy them yourself, the dealer will take care of them all.
Solar energy (solar energy
) refers to the thermal radiation energy of the sun (see the three modes of thermal energy transmission: radiation). Its main manifestation is often called). solar rays. Nowadays, it is typically used to generate electricity or provide energy for water heaters. Since the birth of life on earth, it has relied primarily on thermal radiation energy provided by the sun. Since ancient times, humans have also known how to use sunlight to dry objects and use it as a method of making food, such as crafting. salt and dry the salted fish. With the decline of fossil fuels, solar energy has become an important part of the consumptionhuman consumption of energy and continues to grow. There are two ways to use solar energy: photothermal conversion and photoelectric conversion. Solar power generation is an emerging renewable energy source. Solar energy in a broad sense also includes wind energy, chemical energy, hydropower, etc. on earth.
